Detailed Solution

Concept- Using the unitary method to find the number of notes in Rs 1500.
Total amount in 10 rupee note = Rs10
Total amount in 1000 rupee note = Rs1000
One and a half thousand

= (1 + \frac{1}{2})

1000

= \frac{3}{2} \times 1000 = 1500

Now,
If

Rs 10 = 1 note

Then,

Rs 1500 = \frac{1500 \times 1}{10} notes

Rs1500 contains 150 notes.
Hence, the correct answer is option 3.
